[0003] Filing Date: November 2, 2018

[0004] Title of Invention: Control Device for Controlling an Opening / Closing Member of a Vehicle Technical Field

[0005] The present disclosure generally relates to a control device for controlling an opening / closing member of a vehicle. Background Art

[0006] As an example of a known control device for controlling an opening / closing member of a vehicle, a driving device for an electric sliding door is described in JP2002 - 242533A (hereinafter referred to as Patent Document 1). The known driving device for an electric sliding door drives a motor and automatically opens and closes a sliding door (opening / closing member) by an operation of, for example, an in-vehicle operation switch and a portable operation switch. When the known driving device detects that a user has applied an opening / closing operation force to the door handle of the sliding door that is undergoing an automatic opening / closing operation, the driving device increases the duty ratio of the motor and increases the moving speed of the sliding door. That is, the known driving device enables the sliding door to be automatically opened and closed (automatic opening / closing operation) only by the driving force of the motor, and to be opened and closed at high speed by the user's opening / closing operation force and the driving force of the motor (assisted opening / closing operation).

[0007] The above-described known driving device only deals with changes in the driving speed of the sliding door by changing the duty ratio of the voltage applied to the motor. Therefore, according to the above-described known driving device, it is necessary to select a motor including performance sufficient to respond to changes in the moving speed of the sliding door. In other words, the range in which the moving speed of the sliding door can be changed is affected by the performance of the motor.

[0008] Therefore, there is a need for a control device for controlling an opening / closing member of a vehicle that is less affected by the performance of the motor when performing an automatic opening / closing operation and an assisted opening / closing operation. Summary of the Invention

[0009] According to one aspect of the present disclosure, a control device for controlling an opening and closing member of a vehicle includes a control signal output portion configured to output a motor control signal. The motor control signal is for supplying driving power to a motor. The control device includes an advance angle value setting portion configured to set an advance angle value. The advance angle value is for advancing the phase of the motor control signal during an assisted opening and closing operation compared to during an automatic opening and closing operation. The control device is configured to perform an automatic opening and closing operation and an assisted opening and closing operation. The automatic opening and closing operation causes the opening and closing member of the vehicle to be automatically opened and closed using the driving force of the motor, and the assisted opening and closing operation causes the opening and closing member to be opened and closed in a manner that the driving force of the motor assists the manual operating force applied to the opening and closing member.

[0010] According to the above configuration, during the assisted opening and closing operation, the opening and closing member is operated to be opened and closed using the manual operating force applied by the user and the driving force of the motor, while during the automatic opening and closing operation, the opening and closing member is operated to be opened and closed using the driving force of the motor. Therefore, the moving speed of the opening and closing member during the assisted opening and closing operation may be faster (higher speed) than that during the automatic opening and closing operation. As a result, the rotational speed of the motor during the assisted opening and closing operation tends to be higher than that during the automatic opening and closing operation.

[0011] Therefore, the control device including the above configuration advances the phase of the motor control signal during the assisted opening and closing operation compared to during the automatic opening and closing operation. Thus, the control device for controlling the opening and closing member of the vehicle allows the characteristics of the motor to be the N-T characteristic (rotational speed - torque characteristic) including low rotation and high torque during the automatic opening and closing operation, and allows the characteristics of the motor to be the N-T characteristic including high rotation and low torque during the assisted opening and closing operation. Therefore, when performing the automatic opening and closing operation and the assisted opening and closing operation, the control device is not easily affected by the performance of the motor.

[0012] The control device for controlling the opening and closing member of the vehicle disclosed herein is not easily affected by the performance of the motor during the automatic opening and closing operation and during the assisted opening and closing operation.

[0013] According to another aspect of the present disclosure, the advance angle value setting portion sets the advance angle value during the assisted opening and closing operation, and the advance angle value setting portion does not set the advance angle value during the automatic opening and closing operation.

[0014] According to the above configuration, the control device for controlling the opening and closing member of the vehicle does not need to set the advance angle value during the automatic opening and closing operation. Therefore, it is easy to switch the N-T characteristics of the motor between the automatic opening and closing operation and the assisted opening and closing operation.

[0015] According to another aspect of the present disclosure, in the auxiliary opening / closing operation, when the moving speed of the opening / closing member is high, the advance angle value setting section sets the advance angle value to be larger than that in the case where the moving speed of the opening / closing member is low.

[0016] When performing the auxiliary opening / closing operation, the moving speed of the opening / closing member can be changed according to the magnitude of the manual operating force of the user. In this regard, the control device including the above-described configuration sets the advance angle value according to the speed of the opening / closing member. Therefore, the N-T characteristics of the motor required for the auxiliary opening / closing operation can be made more appropriate.

[0017] According to another aspect of the present disclosure, the control device is configured to obtain the rotational speed of the motor. When the rotational speed of the motor is lower than a predetermined determination rotational speed, the advance angle value is set to a first advance angle value, and when the rotational speed of the motor is equal to or higher than the predetermined determination rotational speed, the advance angle value is set to a second advance angle value, and the second advance angle value is larger than the first advance angle value.

[0018] According to the above configuration, the control device sets the advance angle value according to the rotational speed of the motor. Therefore, the N-T characteristics of the motor required for the auxiliary opening / closing operation can be made more appropriate. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] A vehicle provided with a control device for controlling an opening / closing member of a vehicle according to an embodiment will be described with reference to the accompanying drawings. As Figure 1 shown, the vehicle 1 includes a sliding door 4 that opens and closes a door opening portion 3 provided at a side surface 2s of the vehicle body 2. Specifically, the vehicle 1 includes a plurality of guide rails 5 (5a, 5b, and 5c) extending in the vehicle front-rear direction and a plurality of guide roller units 6 (6a, 6b, and 6c) connected to the plurality of guide rails 5. In the embodiment, for example, three guide rails 5 and three guide roller units 6 are provided. The sliding door 4 is supported at the side surface 2s of the vehicle body 2 via the guide rails 5 and the guide roller units 6. The guide rails 5 and the guide roller units 6 are configured such that the engagement position of the guide roller unit 6 with respect to the corresponding guide rail 5 changes along the extension direction of the guide rail 5. In the above manner, in a state where the sliding door 4 moves along the side surface 2s of the vehicle body 2, the sliding door 4 moves in the vehicle front-rear direction.

[0027] When the sliding door 4 moves in the vehicle front direction, the sliding door 4 becomes a fully closed state in which the sliding door 4 closes the door opening portion 3. When the sliding door 4 moves in the vehicle rear direction, the sliding door 4 becomes a fully open state in which the occupants of the vehicle 1 can enter and exit the vehicle 1 via the door opening portion 3.

[0028] As Figure 2 shown, the sliding door 4 includes a door handle 10 (outer door handle and inner door handle), and the opening and closing operation of the sliding door 4 is performed using the door handle 10. The sliding door 4 is provided with a locking device 11 that includes a fully closed locking portion 11a that restricts the sliding door 4 to the fully closed position and a fully open locking portion 11b that restricts the sliding door 4 to the fully open position. The locking device 11 is connected to the door handle 10 via a remote controller 12.

[0029] At the sliding door 4, when the door handle 10 is operated, the restricted state established by the locking device 11 is released. Further, the sliding door 4 is configured to be manually operated to open and close, and the door handle 10 serves as a holding portion or a gripping portion. For example, the sliding door 4 may be configured such that when an operation switch or a portable device provided in the passenger compartment is operated, the restricted state established by the locking device 11 is released.

[0030] The sliding door 4 includes a door actuator 21 whose drive source is a motor 20. The motor 20 of the door actuator 21 is supplied with drive power from a door ECU 22 (i.e., an example of a control device for controlling an opening / closing member of a vehicle), and thus rotates. That is, the door ECU 22 controls the door actuator 21 via the drive power supplied to the motor 20. A power sliding door device 30 is constructed on the vehicle 1, and the power sliding door device 30 can operate the sliding door 4 to open and close according to the driving force of the motor 20.

[0031] The door actuator 21 includes an opening / closing drive section 31 that drives the sliding door 4 to open and close via a drive cable according to the driving force of the motor 20. The door actuator 21 includes a pulse sensor 32 that outputs a pulse signal Sp synchronized with the operation of the opening / closing drive section 31. The door ECU 22 detects the moving position X and the moving speed Vdr of the sliding door 4 actuated by the door actuator 21 based on the pulse output of the pulse sensor 32.

[0032] The door ECU 22 receives the output signal (operation signal S1) of a first operation section 33 provided, for example, at the door handle 10 in the vehicle compartment or a portable device. The door ECU 22 receives the output signal (switch signal S2) of a second operation section 34 provided around the driver's seat and including a center console. When starting the automatic opening / closing operation to be described later, the user operates the first operation section 33. The second operation section 34 is operated by the user to select which one of the automatic opening / closing operation and the auxiliary opening / closing operation (to be described later) to operate. The door ECU 22 controls the door actuator 21 based on the operation signal S1 and the switch signal S2.

[0033] As Figure 3 shown, the door ECU 22 includes a control target calculation section 41 and a control signal output section 42. The control target calculation section 41 calculates a control target ε for the motor 20, and the control signal output section 42 outputs a motor control signal Smc according to the control target ε. The door ECU 22 includes a drive circuit 43 that outputs drive power to the motor 20 according to the motor control signal Smc. The door ECU 22 includes an advance angle value setting section 44 that sets an advance angle value α for advancing the phase of the motor control signal Smc.

[0034] The control target calculation section 41 calculates the control target ε for the motor 20 based on the operation signal S1 indicating the user's operation request, the moving position X and the moving speed Vdr of the sliding door 4, and various vehicle state quantities including the vehicle speed. The control target ε indicates the rotation direction of the motor 20 and the duty ratio (on-duty ratio) of the motor 20. A brushless motor can be used as the motor 20, and the rotation angle (electrical angle) θ of the motor 20 detected by a rotation angle sensor 45 is input to the control signal output section 42. The control signal output section 42 outputs a motor control signal Smc whose phase changes according to the rotation angle θ of the motor 20.

[0035] As the drive circuit 43, a known PWM inverter composed of a plurality of switching elements (FET: field effect transistor) connected to each other to form a bridge is used. Therefore, regarding the switching elements of the drive circuit 43, the motor control signal Smc is a PWM control signal that adjusts the combination of the on / off pattern according to the rotation angle θ of the motor 20 and the on / off timing corresponding to the conduction duty ratio indicated by the control target ε output from the control target calculation section 41. In the above manner, the drive circuit 43 outputs three-phase (U, V, W) drive power to the motor 20.

[0036] The advance angle value setting section 44 outputs an advance angle value α to the control signal output section 42. The advance angle value α is set based on the switch signal S2 from the second operation section 34 and the rotation speed N of the motor 20. The gate ECU 22 supplies drive power to the motor 20 using the motor control signal Smc whose phase has been advanced by the advance angle value α. In the following description, driving the motor 20 with the motor control signal Smc whose phase has been advanced by the advance angle value α is also referred to as "advance control".

[0037] Next, reference will be made to Figure 4 describe the change in the N-T characteristics of the motor 20 caused by the advance control. Figure 4 shows the N-T characteristics of the motor 20 with different advance angle values α. In Figure 4 In the case where the advance angle value α is the zero (0th) advance angle value α0, the N-T characteristics of the motor 20 are represented by a solid line. In the case where the advance angle value α is the first advance angle value α1, the N-T characteristics of the motor 20 are represented by a dashed line. In the case where the advance angle value α is the second advance angle value α2, the N-T characteristics of the motor 20 are represented by a long dashed-dotted line. Since the 0th advance angle value α0 is "0 (zero)", the case where the advance angle value α is the 0th advance angle value α0 can also be considered as the case where no advance control is performed. The first advance angle value α1 is greater than the 0th advance angle value α0. The second advance angle value α2 is greater than the first advance angle value α1.

[0038] As Figure 4 shown, as the advance angle value α becomes larger, the speed increase operation of the motor 20 due to the execution of the advance control becomes more significant. That is, when the case where no advance control is performed is used as a reference, as the advance angle value α becomes larger, the N-T characteristics of the motor 20 become of the high rotation and low torque type.

[0039] Therefore, when the N-T characteristic of the motor 20 needs to be low rotation and high torque, the door ECU 22 sets the advance angle value α to a smaller value. When the N-T characteristic of the motor 20 needs to be high rotation and low torque, the door ECU 22 sets the advance angle value α to a larger value. The relationship between the advance angle value α of the advance control and the N-T characteristic of the motor 20 can be grasped by, for example, experiments or simulations.

[0040] Next, the opening and closing operations of the sliding door 4 performed by the door ECU 22 will be described. As described above, the door ECU 22 drives the door actuator 21, so that the sliding door 4 operates to open and close. Specifically, the door ECU 22 performs an automatic opening and closing operation and an assisted opening and closing operation. The automatic opening and closing operation causes the sliding door 4 to automatically open and close using the driving force of the motor 20, and the assisted opening and closing operation causes the sliding door 4 to open and close in a manner that the driving force of the motor 20 assists the manual operating force of the user. In the embodiment, the door ECU 22 performs the automatic opening and closing operation when the switch signal S2 is input from the second operation portion 34, and the door ECU 22 performs the assisted opening and closing operation when the switch signal S2 is not input from the second operation portion 34. The manual operating force is the force applied by the user to the sliding door 4 via the door handle 10 to operate the sliding door 4 to open and close.

[0041] The automatic opening and closing operation operates the sliding door 4 to open and close at a relatively low speed only using the driving force of the motor 20, and accordingly, the N-T characteristic of the motor 20 required for the automatic opening and closing operation corresponds to the N-T characteristic of low rotation and high torque. On the other hand, the assisted opening and closing operation operates the sliding door 4 to open and close at a relatively high speed using the manual operating force applied by the user and the driving force of the motor 20, and therefore, the N-T characteristic of the motor 20 required for the assisted opening and closing operation corresponds to the N-T characteristic of high rotation and low torque. In this case, by only increasing the conduction duty ratio of the motor 20, the motor 20 may not be able to output the torque required for the automatic opening and closing operation, or the motor 20 may not be able to rotate at the rotational speed N required for the assisted opening and closing operation.

[0042] Therefore, when performing the assisted opening and closing operation, the advance angle value setting portion 44 (door ECU 22) sets the advance angle value α for advancing the phase of the motor control signal Smc to be larger than when performing the automatic opening and closing operation. Specifically, the advance angle value setting portion 44 does not set the advance angle value α when performing the automatic opening and closing operation, while the advance angle value setting portion 44 sets the advance angle value α greater than 0 (zero) when performing the assisted opening and closing operation. In other words, the advance angle value setting portion 44 sets the advance angle value α to 0 (zero) during the automatic opening and closing operation.

[0043] The moving speed Vdr of the sliding door 4, i.e., the rotational speed N of the motor 20, may increase depending on the magnitude of the manual operating force of the user during the auxiliary opening / closing operation. In this case, simply increasing the conduction duty ratio may not result in the rotational speed N of the motor 20 being the rotational speed N corresponding to the moving speed Vdr of the sliding door 4. Therefore, during the auxiliary opening / closing operation, the door ECU 22 changes the advance angle value α based on the moving speed of the sliding door 4. Specifically, the advance angle value setting section 44 selects the advance angle value α based on the Figure 5 mapping diagram shown in

[0044] Figure 5 A mapping diagram for setting the advance angle value α according to the rotational speed N of the motor 20 is shown. As Figure 5 shown, when the rotational speed N of the motor 20 is the first rotational speed N1, the advance angle value α is the first advance angle value α1, and when the rotational speed N of the motor 20 is the second rotational speed N2, the advance angle value α is the second advance angle value α2, and the second rotational speed N2 is greater than the first rotational speed N1. The first advance angle value α1 is set to be less than the second advance angle value α2. In other words, when the rotational speed N of the motor 20 is less than a predetermined or preset determination rotational speed Nth, the advance angle value α is set to the first advance angle value α1. When the rotational speed N of the motor 20 is equal to or greater than the predetermined determination rotational speed Nth, the advance angle value α is set to the second advance angle value α2.

[0045] Next, the processing performed by the door ECU 22 for the automatic opening / closing operation and the auxiliary opening / closing operation will be described with reference to the Figure 6 flowchart shown in Figure 6 As shown, the door ECU 22 determines whether a switch signal S2 is input from the second operation section 34 (step S11). If a switch signal S2 is input from the second operation section 34 (step S11: Yes), the door ECU 22 determines whether the start condition for the automatic opening / closing operation is satisfied (step S12). For example, the start condition for the automatic opening / closing operation may be a condition satisfied when an operation signal S1 is input from the first operation section 33. If the start condition for the automatic opening / closing operation is not satisfied (step S12: No), the door ECU 22 ends the processing.

[0046] On the other hand, if the start condition for the automatic opening and closing operation is satisfied (Step S12: Yes), the door ECU 22 performs the automatic opening and closing operation (Step S13). That is, the door ECU 22 drives the motor 20 of the door actuator 21 without performing advance control, and causes the sliding door 4 to automatically perform the opening operation and the closing operation. Subsequently, the door ECU 22 determines whether the end condition for the automatic opening and closing operation is satisfied (Step S14). For example, the end condition for the automatic opening and closing operation may be a condition satisfied when a signal for stopping the sliding door 4 is input from the first operation unit 33, a condition satisfied when the sliding door 4 is positioned at the fully closed position or the fully open position, and / or a condition satisfied when the sliding door 4 contacts an obstacle.

[0047] If the end condition for the automatic opening and closing operation is not satisfied (Step S14: No), the door ECU 22 moves the process to Step S13. On the contrary, if the end condition for the automatic opening and closing operation is satisfied (Step S14: Yes), the door ECU 22 stops the motor 20 of the actuator 21 and ends the process.

[0048] If the switch signal S2 is not input from the second operation unit 34 in Step S11 (Step S11: No), the door ECU 22 determines whether the start condition for the auxiliary opening and closing operation is satisfied (Step S15). For example, the start condition for the auxiliary opening and closing operation may be a condition satisfied when the moving speed Vdr of the sliding door 4 is equal to or greater than a predetermined determination speed. If the start condition for the auxiliary opening and closing operation is not satisfied (Step S15: No), the door ECU 22 ends the process.

[0049] On the other hand, if the start condition for the auxiliary opening and closing operation is satisfied (Step S15: Yes), the door ECU 22 obtains the rotational speed N of the motor 20 (Step S16). Then, the door ECU 22 refers to Figure 5 the mapping diagram shown, and sets the advance angle value α corresponding to the rotational speed N of the motor 20 obtained in Step S16 (Step S17). Then, the door ECU 22 performs the auxiliary opening and closing operation (Step S18). That is, the door ECU 22 drives the motor 20 of the door actuator 21 through advance control. In the above manner, the door ECU 22 uses the driving force of the motor 20 to assist the manual operation force of the user, and causes the sliding door 4 to perform the opening operation and the closing operation.

[0050] Subsequently, the door ECU 22 determines whether the end condition of the assisted opening / closing operation is satisfied (step S19). For example, the end condition of the assisted opening / closing operation may be a condition satisfied when the sliding door 4 is in a predetermined position including the fully open position or the fully closed position and the user stops operating the sliding door 4. More specifically, the door ECU 22 may determine that the operation of the user on the sliding door 4 has stopped based on the decrease in the rotational speed N of the motor 20 associated with the decrease in the manual operating force, or based on the increase in the load of the motor 20 associated with the user's attempt to stop the opening / closing operation of the sliding door 4.

[0051] If the end condition of the assisted opening / closing operation is not satisfied (step S19: No), the door ECU 22 moves the process to step S16. On the contrary, if the end condition of the assisted opening / closing operation is satisfied (step S19: Yes), the door ECU 22 stops the motor 20 of the door actuator 21 and ends the process.

[0052] The operations and effects of the embodiment will be described. (1) When performing the assisted opening / closing operation, the door ECU 22 advances the phase of the motor control signal Smc more than the phase during the automatic opening / closing operation. Therefore, the door ECU 22 allows the characteristics of the motor 20 during the automatic opening / closing operation to be the N-T characteristics including low rotation and high torque, and allows the characteristics of the motor 20 during the assisted opening / closing operation to be the N-T characteristics including high rotation and low torque. Without using a motor 20 with high performance, the door ECU 22 can perform the automatic opening / closing operation and the assisted opening / closing operation, where the speeds Vdr of the sliding door 4 are different from each other. Therefore, when performing the automatic opening / closing operation and the assisted opening / closing operation, the door ECU 22 is not easily affected by the performance of the motor 20.

[0053] (2) The door ECU 22 does not set the advance angle value α during the automatic opening / closing operation, while the door ECU 22 sets the advance angle value α to a value greater than 0 (zero) during the assisted opening / closing operation. Therefore, the door ECU 22 can easily switch between the N-T characteristics required for the automatic opening / closing operation and the N-T characteristics required for the assisted opening / closing operation.

[0054] (3) When performing the assisted opening / closing operation, the moving speed Vdr of the sliding door 4 can be changed by the manual operating force of the user. Since the door ECU 22 sets the advance angle value α according to the rotational speed N of the motor 20 (according to the moving speed Vdr of the sliding door 4), the N-T characteristics of the motor 20 required during the assisted opening / closing operation can be made more appropriate.

[0055] Embodiments can be implemented by the following changes and / or modifications. The embodiments and the following modification examples can be carried out in combination with each other without departing from the scope where no technical inconsistency occurs. The door ECU 22 can set the advance angle value α to be greater than 0 (zero) during the automatic opening and closing operation. In this case, it is desirable that the door ECU 22 sets the advance angle value α for the automatic opening and closing operation to be less than the advance angle value α for the assisted opening and closing operation.

[0056] Regardless of the rotational speed N of the motor 20 during the assisted opening and closing operation, the door ECU 22 can set the advance angle value α to a constant value. Figure 5 The shown mapping diagram can be a mapping diagram of the advance angle value α set with respect to the rotational speed N of the motor 20 in three or more levels. Figure 5 The mapping diagram shown in can be a mapping diagram in which the advance angle value α gradually increases as the rotational speed N increases. In this case, Figure 5 The shown mapping diagram can be a mapping diagram in which the advance angle value α changes linearly with respect to the rotational speed N, or a mapping diagram in which the advance angle value α changes non-linearly with respect to the rotational speed N.

[0057] The control device for controlling the opening and closing member of the vehicle, which serves as the door ECU 22, can control the opening and closing operations of the opening and closing members of the vehicle 1 other than the sliding door 4. For example, the opening and closing member to be controlled can be a swing door or a rear door provided at the rear of the vehicle 1.
